The attachment of the Garmin Edge 1040 to a recumbent bike with a centre bar of approx. 35 mm diameter depends on the accessories supplied. As standard, the mounts are suitable for bikes with a diameter of approximately 31.8 mm to 35 mm. If the centre bar measures exactly 35 mm, it might fit, but it is advisable to check the specific dimensions of the supplied bracket or use a suitable extension or adapter if necessary.
